Which expression is equivalent to 14x − 7 + 3(2x − 5)? A) 6x + 12 B) 8x − 12 C) 20x − 22 D) 24x − 15
1 answer:
The given expression is
![14x - 7 + 3(2x - 5)](https://tex.z-dn.net/?f=14x%20-%207%20%2B%203%282x%20-%205%29)
And we have to find the equivalent expression.
First we simplify the given expression by distributing 3 on 2x-5. That is
![= 14x-7+6x-15](https://tex.z-dn.net/?f=%3D%20%2014x-7%2B6x-15)
Now we combine the like terms, that is
![= 14x+6x-7-15 = 20x -22](https://tex.z-dn.net/?f=%3D%2014x%2B6x-7-15%20%3D%2020x%20-22)
And that's the simplified expression. And hence the correct option is C .
